I need a rendering and an stl file of this ring. The size is 6 for the ring. It is a semi tension set. The ring needs to have a sharp edge instead of rounded and it needs to be a low setting. the diamond will sit flush with the band and there needs to be a band of metal right underneath the diamond. the measurements for the diamond are 17.90x10mm. I have several pictures of the styles that I want combined into the ring but I can only attach one right now.
